METAL AND RUBBER SHOE-SOLE.

Specification of Letters Patent.

Patented June 3, 1919.

Application filed February 5, 1918. Serial No. 215,507.

useful Improvements in Metal and Rubber Shoe-Soles, of which thefollowing is a specification. V

This invention relates to a combination rubber and metal shoe sole andhas for its object the production of a simple and eiii cient means forsupporting the yieldable tread portion in engagementwith a metallic shoesole which may be attached to the sole of a shoe. 7 7

Another object of this invention is the production of a simple andeilicient means for securing or holding the several tread sections oithe shoe sole together so as to permit the same to freely move under theaction of the feet after the shoe sole has been applied to a shoe.

With these and other objects in view, this invention consists of certainnovel constructions, combinations, and arrangements of parts as will behereinafter fully described and claimed.

In the drawings: r V

Figure 1 is a bottom plan view of the shoe sole, 1 Fig. 2 is a sideelevation thereof, 7

Fig. 3 is a section taken on line 3-3 of Fig. 1, r

Fig. 4 is a fragmentary bottom plan view of a portion of the shoe soleshowing the rubber tread blocks removed therefrom,

Fig. 6 is a section taken on line 6-6 of Fig. 3, r

Fig. 7 is a section taken on line 7-7 of Fig. 4. V V

By referring to the drawings, it will be seen that 1 designates the heelsection which comprises an outer flange 2 and a plurality oflongitudinally extending ribs 3. These ribs 3 are also engaged by meansof the transversely extending ribs 4: for the purpose of dividing theheel 1 into a plurality of pockets 5. A rubber cushion block 6 is placedwithin each of the pockets 5 as shown in Fig. 1, and is adapted toconstitute a yieldable tread for the heel section 1. The heel section 1is adapted to be secured to the heel of a shoe by means of suitablescrews '7, these screws 7 passing through the junction is a sectiontaken on line 5-5 of 7 point of certain of the longitudinally andtransversely extending ribs 3 and 4, in this way firmly holding the heelsection 1 in engagement with the heel of a shoe.

A sole section 8 is used in conjunction with the heel section and thissole section 8 comprises an arch section 9, a toe section 10 and a pairof intermediate sections 11. The arch section 9 is provided with asecuring lip' 12, uponthe inner ends thereof,

which securing lip 12 is provided with suit- 7 able securing apertures13 formed near the inner edge thereof for the purpose of permittingsuitable screws to pass therethrough and allow the arch section 12 to'besecured to the arch of a shoe. sect-ions oi the sole section of the shoe8 comprises a plurality of longitudinally extending ribs 1% andplurality of transverselyextend ng ribs 15, these rlbs 14 and 15 being 7arranged at substantially right angles to each other for the purpose ofproducing Each of the plurality of cushion receiving pockets '16.

An outer retaining rib 17 extends around the entire side edge of thesole section 8 as shown in Figs. 1 and 2 of the drawings, forthe'purpose of constituting an outer retaining flange for the sole section.A yieldable or rubber cushion 18 is provided in each of the pockets 16and projects beyond the i outer edge of the flanges and ribs carried bythe sole section about one-sixteenth of an inch. It is of course,understood that the sole may be constructed of any suitable ma terialfor example, the sole may be made of aluminum or steel, and that anyyieldable substance may be employed in place of the rubber cushion whichhas been previously specified. The respective sections of the solesection 8 are preferably held in engagementwith the sole of a shoe'bymeans of suitable screws 19, these screws 19 pass ing through theapertures 20 formed in the sole sections 8, the sole sections 8 havingthe socket or aperture 20 so formed as to permit the screw head of thescrews 19 'to' fit within the countersunk portion 21 of the apertures20. It is of course desired to have the securing means or screws extendflush with the outer edge or face of the transversely extending ribs.The intermediate sections 11 are provided with a convex-shaped end and aconcave-shaped end, the concave shaped end of one section interlockedwith the convex shaped end of the other section. The toe sections 10 areprovided with a concave shaped inner end 22 which fits over the convexshaped end of the section of one of the intermediate sections 11 asshown in Fig. 2 and the arch 9 is provided with a convex shaped endwhich is adapted to fit within the concave shaped end of one of theintermediate sections 11 as shown in Fig. 2.

In this way the sole section 8 will be yieldable to accommodate itselfto the bend of the foot of the wearer, in this way relievingconsiderable strain from the wearers foot as would be the case if thesole section 8 were formed entirely rigid. It of course is necessary toprovide only slight yieldable action between the respective archsection, toe sections, and intermediate sections of the sole section 8owing to the concavo-convex connection between the respective sectionsas shown clearly in Figs. 2 and 5 of the drawings, which allows a sli htyieldable movement to take place.

ach of the yieldable blocks 18 and 6 are provided with beveled sideedges 24: for the purpose of preventing the outer edges of the yieldableblocks 6 and 18 from overhanging the ribs of the heel and sole sections.

The arch sections and toe sections are held in engagement with theintermediate sections by meansv of the retaining rods 25, theseretaining rods 25 being provided withsuitable notches. or other securingmeans 26 at the respective ends thereof for the purpose of retaining therespective sections of the sole sections 18 in proper relation. Theseretaining rods or wires 25 extend longitudinally through the solesection as in dicated clearly in F igs. 1, 4 and 5 and necessarily passthrough the transversely extending ribs 15 of the respective sections ofthe toe sections. Each of the ribs 15 is provided with an aperture 27,these apertures 27 being provided with Widenedouter edges 28 as shown inFig. 6 for permitting a slight yieldable movement or swinging movementof the sections uponthe rods or wires 25 without fearof breaking orsnapping the rods 25.

From the foregoing description, it will be seen that a very simple andefiicient me tallic sole has been produced which may be attached to thesole of the shoe as well as the heel thereof and thereby the soleportions of the shoe sole may accommodate itself to position of the footwhile the wearer Copies of this patent may be obtained for five centseach, by addressing the of the device is walking. Furthermore themetallic portion of the sole will constitute an efiicient reinforcingmeans and hold the shoe against unnecessary wear and at the same time aneflicient cushion has been pro duced in the nature of rubber orresilient blocks 6 and 18, these blocks being capable of being renewedwhen it is so desired or after the block has become worn.

It of course should be understood that it is not necessary or desirousto limit the present invention to any form of material although it ofcourse is desired to have the device constructed as light as possibleand so construct the sole as to prevent the same from being easily wornor accidentally broken.

What is claimed is:

1. A shoe sole comprising a plurality of sections, each section beingprovided with a plurality of longitudinally and transversely extendingrib portions for producing a plurality of rectangular cushion receivingpockets upon the under face of the sole, some of said transverselyextending rib portions having transversely extending apertures providedwith outwardly flared ends, retaining rods extending through saidapertures and cushions positioned in said peck ets, and said sole beingprovided with apertures at the junction of some of said longitudinallyand transversely extending ribs for the purpose of permitting fastenerswhich attach the sole to the shoe to pass through the sole.

2. A shoe sole comprising a body constituting a plurality of sections,said sections provided with curved abutting edges to permit theconformation of one section tothe other as one section is swung relativeto the other, said sections provided with a plurality of longitudinallyand transversely extending ribs for producing cushion receiving pocketssome of said transversely ex-tending'ribs provided with apen tureshaving outwardly flared outer ends, tying rods extending through saidapertures and holding said sections firmly together, and cushionspositioned within said pockets.

In testimony whereof I aflix my signature in presence of two witnesses.
